4 Positioning
During positioning consider these elements:
• Technical spaces requested by the unit
• Electrical connections
• Water connections
• Spaces for air exhaust and intake
4.1 Functional spaces
Functional spaces are designed to:
• guarantee good unit operation
• carry out maintenance operations
• protect authorized operators and exposed people
Respect all functional spaces indicated in the DIMENSIONS section.
Double all functional spaces if two or more unit are aligned.
4.2 Positioning
Units are designed to be installed:
• EXTERNAL
• in xed positions
Limit vibration transmission:
• use antivibration devices on unit bearing points
• install exible joints on the hydraulic connections
Choose the installation place according to the following criteria:
• Customer approval
• safe accessible position
• technical spaces requested by the unit
• spaces for the air intake/exhaust
• The device prevents any impurity in the water circuit to dirt the heat exchanger.
• verify unit weight and bearing point capacity
• verify that all bearing points are aligned and leveled
• install the unit raised from the ground
• max. distance allowed by the electrical connections
Prefer places where the unit doesn’t disturb the neighbours.
Avoid installations next to bedrooms or windows.
A correct circulation of the air is mandatory to guarantee the good unit operating.
Avoid therefore:
• obstacles to the airow
• diculty of exchange
• leaves or other foreign bodies that can obstruct the air coil
• winds that hinder or favour the airow
• heat or pollution sources close to the unit (chimneys, extractors etc..)
• stratication (cold air that stagnates at the bottom)
• recirculation (expelled air that is sucked in again)
• incorrect positioning, close to very high walls, attics or in angles that could give rise to stratication or recirculation phenomenons
Ignoring the previous indications could:
• reduce energy eciency
• alarm lockout due to HIGH PRESSURE (in summer) or LOW PRESSURE (in winter)

M0Q940G14-03 WSAT-XIN 21-171 11
A. Keep the min. distances from the podestrian areas.
B. Provide windbreaks in locations with strong winds.
C. Avoid snow accumulations on batteries.
D. Install the unit lifted from the ground.
E. Provide a protection.

5 Water connections
5.1 Water quality
Water features
• conrming to local regulations
• total hardness < 14°fr
• within the limits indicated by table
The water quality must be checked by qualied personnel.
Water with inadequate characteristics can cause:
• pressure drop increase
• reduces energy eciency
• increased corrosion potential
Provide a water treatment system if values fall outside the limits.
The warranty does not cover damages caused by limestone formations, deposits and impurities
from the water supply and / or failure from failed system clearing to clean system.
5.2 Risk of freezing
If the unit or the relative water connections are subject to temperatures close to 0°C:
• mix water with glycol, or
• safeguard the pipes with heating cables placed under the insulation, or
• empty the system in cases of long non-use
5.3 Anti-freeze solution
The use of an anti-freeze solution results in an increase in pressure drop.
Make sure that the glycol type utilized is inhibited (not corrosive) and compatible with the water circuit components.
Do not use dierent glicol mixture (i.e. ethylene with propylene).
5.4 Water ow-rate
The project water-ow must be:
• inside the exchanger operating limits (see the TECHNICAL INFORMATION section)
• guarantee, also with variable system conditions (for example in systems where some circuits are bypassed in particular situations).

5.5 Operation sequence
Close all vent valves in the high points of the unit hydraulic circuit
Close all drain valves in the low points of the unit hydraulic circuit:
• Heat exchangers
• Pumps
• collectors
• storage tank
• free-cooling coil
1. Carefully wash the system with clean water: ll and drain the system several times.
2. Apply additives to prevent corrosion, fouling, formation of mud and algae.
3. Fill the plant
4. Execute leakage test.
5. Isolate the pipes to avoid heat dispersions and formation of condensate.
6. Leave various point of service free (wells, vent-holes etc).
Neglecting the washing will lead to several lter cleaning interventions and at worst cases can cause damages to the exchangers and the
other parts.
5.6 Recommended connection
The installer must dene:
• component type
• position in system
Water input output position:

3. Before starting work, ensure the unit is isolated, unable to be turned on and a safety sign used.
4. Ensure correct earth connection.
5. Ensure cables are suitably protected.
6. Before powering up the unit, make sure that all the protections that were removed during the electrical connection work have been
restored.
6.3 Signals / data lines
Do not exceed the maximum power allowed, which varies, according to the type of signal.
Lay the cables far from power cables or cables having a dierent tension and that are able to emit electromagnetic disturbances.
Do not lay the cable near devices which can generate electromagnetic interferences.
Do not lay the cables parallel to other cables, cable crossings are possible, only if laid at 90°.
Connect the screen to the ground, only if there aren’t disturbances.
Guarantee the continuity of the screen during the entire extension of the cable.
Respect impendency, capacity and attenuation indications.
